6e156075b0 avfilter: Add blue and violet noise generation filters
For the blue and violet noise, I took the pink and brown noise
respectively and subtracted the offsets instead of adding them. When I
eyeball the frequency spectrum of the resulting outputs it looks correct
to me, i.e. the blue graph appears to be a mirror image of the pink, and
the same can be said of the violet and the brown. I did not do anything
else to confirm the correctness.

70143a3954 dxva: add support for new dxva2 and d3d11 hwaccel APIs
This also adds support to avconv (which is trivial due to the new
hwaccel API being generic enough).

The new decoder setup code in dxva2.c is significantly based on work by
Steve Lhomme <robux4@gmail.com>, but with heavy changes/rewrites.

Merges Libav commit f9e7a2f95a7194a8736cc1416a03a1a0155a3e9f.
Also adds untested VP9 support.
The check for DXVA2 COBJs is removed. Just update your MinGW to
something newer than a 5 year old release.

3303511f33 lavu: add new D3D11 pixfmt and hwcontext
To be used with the new d3d11 hwaccel decode API.

With the new hwaccel API, we don't want surfaces to depend on the
decoder (other than the required dimension and format). The old D3D11VA
pixfmt uses ID3D11VideoDecoderOutputView pointers, which include the
decoder configuration, and thus is incompatible with the new hwaccel
API. This patch introduces AV_PIX_FMT_D3D11, which uses ID3D11Texture2D
and an index. It's simpler and compatible with the new hwaccel API.

The introduced hwcontext supports only the new pixfmt.

Frame upload code untested.

Significantly based on work by Steve Lhomme <robux4@gmail.com>, but with
heavy changes/rewrites.

Merges Libav commit fff90422d181744cd75dbf011687ee7095f02875.

5aea18cbd8 doc/filters: Correct scale doc regarding w/h <= 0
According to libavfilter/scale.c, if the width and height are both
less than or equal to 0 then the input size is used for both
dimensions. It does not need to be -1. -1:-1 is the same as 0:0 which
is the same as -10:-42, etc.

if (w < 0 && h < 0)
    eval_w = eval_h = 0;

The documentation for the zscale filter has also been updated since the
behavior is identical.
